VPN Instructions
Exchange Hosting Service provides a VPN (Virtual Private Network)
capability, so you can connect to the servers through VPN if you choose.
Using VPN requires the use of a HOSTS file, and it
requires a customized vpn HOSTS file which is slightly different from the
general one. See:
HOSTSfileinstructions-vpn.htm
Using VPN also requires a modification to the Connectivity
Test. You will need to follow the VPN
Instructions and create the VPN connection before doing the ping test. The
VPN must be connected for the ping test to work.
The software for making a VPN connection is included in Windows
XP and
Windows 2000. Earlier versions of Windows require the installation of
additional software to support VPN. Contact us for additional information if
you are using an older version of Windows.
If you use a personal firewall or broadband router, or if there are
firewalls between the VPN client and the VPN server, TCP port 1723 and IP
protocol 47 (GRE) must be enabled on all firewalls and routers that are
between the VPN client and the VPN server. By default, most corporate firewalls will
prevent VPN connections, and will need to be configured to allow VPN.
Step 1.
Connecting through VPN requires the use of a HOSTS file. See
HOSTS File Instructions
for help setting up a HOSTS file on your computer.
This is not optional, in order to successfully connect Outlook to
Exchange over the VPN, you must use a hosts file, and the hosts file must be
configured for VPN use, as shown in our hosts file instructions.
In the hosts file instructions, make note of the difference between the
hosts file for general, non-vpn use and the vpn hosts file. The IP addresses
in the vpn hosts file start with 10 instead of 65.
Step 2.
Create the VPN connection. Instructions are
provided separately below for Windows 2000 and
Windows XP.
Open Start > Settings > Network and Dial-up Connections >Make New
connection. Click Next.
Select “Connect to a private network through the Internet” and click
Next. See screen shot.

On the next page of the wizard, if you use a dial-up connection to
connect to the Internet, click Automatically dial this initial connection,
and then, in the list, click your dial-up Internet connection.
If you use a full-time connection (such as a rotten cable company that
blocks your access to port 135), click "Do not dial the initial connection."
See screen shot.

On the next page of the wizard, enter VPN.WEBVILLE.NET as the destination
and click Next. See screen shot.

On the next page of the wizard, select “Only for Myself” and click Next.
Name your VPN connection whatever you like, and choose whether to “add a shortcut
to my desktop.” Click Finish to close the wizard.
Don't click Connect just yet. If it asks you whether you want to dial,
say no. You need to edit the properties first. Find the connection on your
desktop or in Network Connections, right click it and choose Properties, to edit the properties of
the new VPN connection.
Click the Networking tab of the VPN connection properties. See screen
shot.

Click Internet Protocol (TCP/IP) in the list of components, then click
the Properties button. See screen shot.

Click the Advanced button. See screen shot.

This is key. Clear the check box marked "Use default gateway on remote
network." You do not want to use the default gateway on the remote network.
Now just click OK 3 times to confirm the changes.
Skip the Windows XP section below and see step 4 at the bottom of this page.
Open Start > Control Panel > Network Connections.
Under Network Tasks, choose Create a New Connection. The New Connection
Wizard will appear. Click Next on the wizard's welcome page.
Choose Connect to the Network at my Workplace and click Next. See screen
shot.

Choose Virtual Private Network connection and click Next. See screen
shot.

Name the connection anything you like and click Next. See screen shot.

On the next page of the wizard, if you use a dial-up connection to
connect to the Internet, click Automatically dial this initial connection,
and then, in the list, click your dial-up Internet connection.
If you use a full-time connection (such as a rotten cable company that
blocks your access to port 135), click "Do not dial the initial connection."
See screen shot.

Type VPN.WEBVILLE.NET for the name of the VPN server and click Next. See
screen shot.

On the next page of the wizard, select “My use only” and click Next.
Choose whether to add a shortcut to your desktop and click Finish to
close the wizard.
Don't click Connect just yet. Click Properties, to edit the properties of
the VPN connection.
Click the Networking tab of the VPN connection properties. See screen
shot.

Click Internet Protocol (TCP/IP) in the list of components, then click
the Properties button. See screen shot.

Click the Advanced button. See screen shot.

This is key. Clear the check box marked "Use default gateway on remote
network." You do not want to use the default gateway on the remote network.
Now just click OK 3 times to confirm the changes and you should be
all set.
Step 3.
Initiate the VPN connection. The VPN connection needs to be established
before you start Outlook. It needs to remain established the entire time
Outlook is running, if you're working in the online mode, (not offline). Use
the same username and password for the VPN connection that you use for your
mailbox.
Step 4.
Verify the VPN configuration with a ping test. To verify your
configuration, start the VPN connection and try the ping test.
Click here for instructions on using ping
to test a connection. Ping Shelley3 when your VPN connection is active and
you should get replies from 10.115.231.153 not 65.115.231.153.
If you get replies from 65.115.231.153, then your HOSTS file is not
configured correctly, and your system is continuing to use the external
address of the server instead of the internal (vpn) address. This would mean
you need to go back to step 1, and fix your HOSTS file.
If you get replies from 10.115.231.153, then go to step 5.
Step 5.
Theoretically, this step should not be necessary, but a number of people
have needed to create a new profile at this point. Their old profile won't
work, but a new profile will.
While connected to VPN, start the profile wizard and create a new Outlook
profile. Hitting the check name button is the critical moment. If that
works, you should be good to go.
See
Outlook Profiles for the steps to create
an Outlook profile. Follow the instructions for creating a traditional
profile, not RPC-over-HTTP.
